| Science fiction, whether print, TV, or movies, has a tradition of making up new swear words (or sometimes borrowing them from languages other than the one the SF is written/spoken in). Part of this is the awareness that language isn't always the same, and in the future, or in another galaxy, the same concepts wouldn't serve as cuss words. (It also allows the writers to have characters swear without being censored, sometimes by being only very slightly different from everyday swear words.)
